N. Y., a corporation of New York Application February 17, 1932. Serial No. 593,472

This invention relates to bags and has for an object to provide a bag formed in part of a highly transparent material such as "Cellophane and in part of a less transparent material such a's glassine or ordinary opaque paper.

It is a. primary object of the invention to providea gusseted bag of the kind referred to wherein the seams formed by the junction of the different materials of which the bag is made are locate@ within the gussets and are therefore protected during the drying, storing, shipping and handling prior to the lling of thebag.

Other objects and advantages will hereinafter appear.

In the drawing forming part of this specification:

Figure 1 is a View in front elevation of a bag embodying features of the invention; n

Figure 2 is a transverse, sectional view taken through the bag of Figure 1;

Figure' 3 is a view similar to Figure 2 illustrating a modified form of bag 'embodying the invention;

Figure 4 is `Va view similar to Figures 2 and 3 illustrating a further modified form of bag embodying the invention; and

Figure 5 is a front view of a bag similar to that of Figure 1, but having the front and back cut smoothly.

The bag of Figures 1 and 2 comprises a front piece C of cellophane or other suitable transparent material and a back piece G of glassine or other suitable, less transparent material. The piece G has marginal portions 1 folded inward. AThe piece C has marginal portions 2 folded inward and extreme marginal portions 3 folded outward. The marginal portions 3 extend between the body portion of back piece G and the inner margins or borders lof marginal portions 1, and are adhesively united to the latter. The two marginalv portions 1 and 2 jointly form a gusset within which the seam formed by the adhesive union of marginal portions 2 and 3 is located. The gusseted tube formed by the pieces C and G is made into a bag as illustrated in the usual way by striking off the front and backunequally along toothed members, folding over an end portion 4 of the tube, and pasting it against the back of the bag.

The bag of Figure 3 is generally similar to that of Figures l and 2 but differs from it in that the marginal extremities of the piece G are folded outward to provide marginal portions 5, while the infolded marginal portions of the piece C lie against and are adhesively united to the outer faces of these marginal portions 5.

The bag of Figure 4 is identical with that of Figure 3, with the sole exception that out-turned marginal portions 6 are provided upon the piece C and are adhesively united to the outer faces of the inturned marginal portions of the piece G.

In every instance the bag is completed in the manner described in connection with Figures 1 and 2 by folding over and pasting an end por- `tion against the back of the bag.

The `bag of Figure 5 is like that of Figure 1 in all respects except that lthe end edges of the front and back are not serrated, but are smoothly cut. The cellophane part is strongly resistant to tearing when cut in this manner. The bags of Figures 2 to 4 may be cut in the saine manner as the bag of Figure 5.

In each of the constructions described, a bag is provided which is transparent throughout the full length and width of its face and throughout a portion of the width of its sides.

I have described what I believe to be the best embodiment of my invention. I do not wish, however, to be conilned to theA embodiment shown but what I desire to cover by Letters Patent is set forth in the appended claims.

I claim:

1. A bag composed of a front piece of transparent material and a back piece of less transparent material, said pieces having marginal portions thereof folded inward t0 jointly form gussets and being adhesively united to `one another within the gussets.

2. A bag as set forth in claim 1 wherein the front piece has extreme marginal portions thereof folded around the inner edges of the back pieces and adhesively united to the margins of the back piece.

3. A bag as set forth in claim 1 whereinthe inturned marginal portions of the back piece are provided with out-tumed marginal extremities which are superposed upon and adheslvely united to the inturned marginal portions of the front piece.

4. A bag as set forth in claim 1 wherein Vthe inturned marginal portions of one ofthe pieces are provided with out-turned marginal extremities and wherein the inturned marginal portions of the other piece are superposed upon and adhesively united to said out-turned marginal ex` tremities.
